Namecheap API tools (16, 2 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • check_connection

    Verify the Namecheap API connection and credentials. Returns the account balance summary — a lightweight call that confirms the API user, key, and IP whitelist are all working.

  • check_domains

    Check availability (and premium pricing) for one or more domains. Max 50 per call.

  • get_dns_hosts

    Get all DNS host records (A, AAAA, CNAME, MX, TXT, URL, etc.) for a domain.

  • get_domain_contacts

    Get the Registrant, Tech, Admin, and AuxBilling contact details for a domain.

  • get_domain_info

    Get detailed info for one domain: status, created/expiry dates, WhoisGuard, DNS provider, and modification rights.

  • get_email_forwardingwrite action

    Get email forwarding settings (mailbox → forward-to) for a domain.

  • get_nameservers

    Get the nameservers associated with a domain, and whether it uses Namecheap's default DNS.

  • get_pricing

    Get Namecheap pricing for a product type (e.g. DOMAIN register/renew/transfer). Cache results — this is a heavy endpoint.

  • get_registrar_lock

    Get the registrar lock status for a domain.

  • list_domains

    List domains in the account, with creation/expiry dates, lock status, auto-renew, and WhoisGuard status. Supports paging and search.

  • list_ssl_certificates

    List SSL certificates in the account, with type, host name, status, and expiry.

  • set_custom_nameservers

    Point a domain at custom nameservers. NOTE: Namecheap host records, URL/email forwarding stop working while custom nameservers are in use.

  • set_default_dns

    Switch a domain to Namecheap's default (BasicDNS) nameservers. Required for Namecheap host records, URL/email forwarding.

  • set_dns_hosts

    Replace ALL DNS host records for a domain. WARNING: this is destructive — Namecheap deletes any record not included here, so you must pass the COMPLETE desired record set (call get_dns_hosts first, merge your changes, then send everything). Switches the domain to Namecheap DNS if needed.

  • set_email_forwardingwrite action

    Set email forwarding rules for a domain. Replaces the full forwarding set (pass all rules you want to keep).

  • set_registrar_lock

    Lock or unlock a domain at the registrar (theft protection). Unlock before initiating an outbound transfer.

Install Namecheap API in Claude Code, Cursor or VS Code

Runs npx -y namecheap-api-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Namecheap API repository's README, as published. We do not edit it. Read it on GitHub

namecheap-api-mcp

MCP server for the Namecheap API — manage domains, DNS, contacts, registrar locks, and view SSL certificates and pricing, straight from your AI assistant.

Built for Claude Code and any MCP-compatible AI tool.

Part of The SEO Engine toolkit by Rex Jones — AI-powered SEO and social media tooling for agencies and businesses.

Safety model

This server ships read + safe-write tools only. It can read your account and change DNS / nameserver / forwarding / lock configuration (all reversible), but it deliberately excludes anything that spends money or is irreversible: no domain registration, renewal, reactivation, transfers, SSL purchase/activation, add-funds, or account/address mutation. You can fork and add those if you need them.

Quick start

1. Enable Namecheap API access

  1. Go to Profile → Tools → Namecheap API Access and toggle it ON. (Production access requires account eligibility: 20+ domains, OR a $50+ balance, OR $50+ lifetime spend.)
  2. Copy your API key.
  3. Whitelist the public IPv4 of the machine that will run this server (the API rejects any non-whitelisted IP with error 1011150).

2. Configure your MCP client

{
  "mcpServers": {
    "namecheap": {
      "command": "npx",
      "args": ["-y", "namecheap-api-mcp"],
      "env": {
        "NAMECHEAP_API_USER": "your_username",
        "NAMECHEAP_API_KEY": "your_api_key",
        "NAMECHEAP_CLIENT_IP": "your.whitelisted.ip.v4"
      }
    }
  }
}

Option: clone and build

git clone https://github.com/lanternrow/namecheap-api-mcp.git
cd namecheap-api-mcp
npm install
npm run build

Then point your client at node /path/to/namecheap-api-mcp/dist/index.js. For local credentials you can keep a gitignored .env (copy .env.example) and launch with Node's native flag: node --env-file=.env dist/index.js.
